Analysis of natural regression and influencing factors of HSIL in the cervix of childbearing age patients / 中华妇产科杂志

Objective: To investigate the natural regression and related factors of high-grade squamous intraepithelial lesion (HSIL) in the cervix of childbearing age women, and to evaluate the applicability of conservative management for future fertility needs. Methods: This study included 275 patients of reproductive age with fertility needs, who were diagnosed as HSIL by biopsy from April 30, 2015 to April 30, 2022, including 229 cases (83.3%) cervical intraepithelial neoplasia (CIN) Ⅱ and 46 cases (16.7%) CIN Ⅱ-Ⅲ. They were followed-up without immediate surgery in the First Affiliated Hospital of Nanjing Medical University. The median follow-up time was 12 months (range: 3-66 months). The regression, persistence and progression of lesions in patients with HSIL were analyzed during the follow-up period, the influencing factors related to regression and the time of regression were analyzed. Results: (1) Of the 275 HSIL patients, 213 cases (77.5%, 213/275) experienced regression of the lesion during the follow-up period. In 229 CIN Ⅱ patients, 180 cases (78.6%) regressed, 21 cases (9.2%) persisted, and 28 cases (12.2%) progressed. In 46 CIN Ⅱ-Ⅲ patients, 33 cases (71.7%) regressed, 12 cases (26.1%) persisted, and 1 case (2.2%) progressed to invasive squamous cell carcinoma stage Ⅰ a1. There was no significant difference in the regression rate between the two groups (χ2=1.03, P=0.309). (2) The average age at diagnosis, age <25 years old at diagnosis were independent influencing factor of HSIL regression in univariate analysis (all P<0.05). There was no significant difference between HSIL regression and pathological grading, the severity of screening results, human papillomavirus (HPV) genotype, colposcopy image characteristics, number of biopsies during follow-up and pregnancy experience (all P>0.05). (3) The median regression times for patients aged ≥25 years and <25 years at diagnosis were 15 and 12 months, respectively. Kaplan-Meier analysis showed that age ≥25 years at diagnosis significantly increased the median regression time compared to <25 years (χ2=6.02, P=0.014). Conclusions: For HSIL patients of childbearing age, conservative management without immediate surgical intervention is preferred if CINⅡ is fully evaluated through colposcopy examination. Age ≥25 years at diagnosis is a risk factor affecting the prognosis of HSIL patients.

Risk Profile of High-grade Cervical Lesions and Cervical Cancer Considering the Combination of Cytology, HPV Genotype, and Age among Women Undergoing Colposcopy / Perfil de risco de lesões cervicais de alto grau e câncer cervical considerando a combinação de citologia, genótipo do HPV e idade entre mulheres submetidas a colposcopia

Abstract Objective The present study aims to establish a risk profile for high-grade cervical lesions and cervical cancer (CIN2 + ) in women undergoing colposcopy at the Hospital do Câncer de Barretos, through the analysis of Human Papillomavirus (HPV) infection, cervical cytology, and patient's age. Methods Retrospective cross-sectional study based on a computerized database of women aged ≥ 18 years old who underwent colposcopy at the Prevention Department of the Hospital do Câncer de Barretos from 2017 to 2019. Results A total of 3,411 women were included, 58.0% were positive for high-risk-HPV test, with a higher prevalence of CIN2+ for HPV16 (30.3%) and other HPV (45.0%). Cytological findings that suggest invasive cervical cancer (squamous cells or adenocarcinoma), regardless of the status of HPV test, showed 100% diagnosis of CIN2 + , while atypias that suggest high-grade lesions, HSIL and ASC-H, positive for HPV test, showed in 86 and 55.2%, respectively, diagnosis of CIN2 + . ASC-H cytological results among women aged > 40 years old and negative HPV were mainly associated with benign findings. We observed that ≤ CIN1 has a higher prevalence among older women with negative HPV, while for high-grade lesions there is an increase among young women HPV16- and/or 18-positive. In cancer diagnosis, we observed a predominance of HPV 16/18 regardless of the age group. Conclusion The highest risks of precursor lesions and cervical cancer were found among women with positive HPV 16/18 tests and severe cytological atypia in population screening tests. In addition, cytological findings of ASC-H HPV negative in women > 40 years old usually represent benign findings in histological investigation.

Resumo Objetivo Estabelecer um perfil de risco de lesões intraepiteliais de alto grau e câncer do colo do útero (NIC2 + ) em mulheres submetidas a colposcopia considerando-se a infecção pelo papilomavírus humano (HPV), citologia cervical e idade. Métodos Estudo retrospectivo transversal em banco de dados informatizado de mulheres com idade ≥ 18 anos que realizaram colposcopia no departamento de Prevenção de Câncer no Hospital do Câncer de Barretos/SP no período de 2017 a 2019. Resultados Foram incluídas 3.411 mulheres, sendo 58,0% positivas para HPV de alto risco, e maior prevalência de NIC2+ para HPV16 (30,3%) e outros HPV (45,0%). Resultados citológicos sugestivos de lesões invasivas (epidermoide ou adenocarcinoma), independente do teste de HPV, apresentaram 100% de diagnóstico NIC2 + , enquanto atipias sugestivas de lesões de alto grau, HSIL e ASC-H, associados a HPV positivo, apresentaram 86 e 55,2%, respectivamente. Resultados citológicos de ASC-H entre mulheres > 40 anos e HPV negativo foram associados principalmente a achados benignos. Observamos que ≤ NIC1 apresenta uma maior prevalência entre mulheres mais velhas com HPV negativo, enquanto para lesões de alto grau, há um aumento entre mulheres mais jovens positivas para HPV16/18. Para diagnóstico de câncer, observamos que há um predomínio de HPV16/18 independente da faixa etária. Conclusão Foi identificado maior risco de lesões precursoras e câncer entre mulheres com HPV 16/18 positivo e atipias citológicas graves em testes de rastreio populacional. Além disso, resultados citológicos de ASC-H quando associados a HPV negativo com idade > 40 anos habitualmente representam achados benignos em investigação histológica.

Alterações em exames citopatológicos realizados em Unidade Básica de Saúde: um estudo analítico transversal / Alterations in cytopathological tests performed in a Basic Health Unit: a cross-cutting analytical study

Objetivo: Com o presente estudo, buscou-se verificar a quantidade de exames de colpocitologia oncótica coletados em Unidade Básica de Saúde (UBS) escolhida, determinar quantas e quais são as alterações encontradas nesses exames e quais foram as condutas e acompanhamentos realizados em pacientes com exames alterados. Métodos: Foram analisados 446 exames de colpocitologia oncótica realizados em uma UBS do centro-oeste do Paraná. As pacientes com exame alterado foram selecionadas e foi feita uma análise desses prontuários a fim de verificar a conduta e o acompanhamento dessas pacientes. Resultados: Foram encontrados 32 exames com alterações, sendo três de uma mesma paciente. Dessas 30 pacientes, a grande maioria correspondia a células escamosas atípicas de significado indeterminado (ASC-US), possivelmente não neoplásicas, e 28 pacientes retornaram para receber uma conduta inicial, sendo principalmente o encaminhamento para a coleta de novo preventivo em seis meses ao serviço de oncologia clínica. Conclusão: O presente estudo concluiu que a hipótese principal foi verdadeira, a qual foi descrita como prevalência significativa de lesões intraepiteliais de alto grau, embora não seja a mais frequente, e descontinuidade por parte das pacientes que obtiveram esse resultado. Além disso, notou-se grande encaminhamento à atenção terciária, o que não é indicado pelo Ministério da Saúde.(AU)

Objective: With the present study, we sought to verify the amount of cytopathological tests collected in the chosen basic health unit, to determine how many and what are the alterations found in these tests and what were the conducts and follow-ups performed in patients with altered exams. Methods: We analyzed 446 preventive tests performed in a basic health unit in the Midwest of Paraná, and patients with altered examination were selected and an analysis of these medical records was made in order to verify the conduct and follow-up of the patients. Results: Thirty-two tests with alterations were performed, 3 of which were the same patient. Of these 30 patients, the vast majority corresponded to atypical cells of squamous meaning ­ possibly non-neoplastic (ASC-US), and 28 patients returned to receive an initial approach, mainly being referred to the collection of preventive new in 6 months and to the clinical oncology service. Conclusion: The present study concluded that the main hypothesis was true, which was described as a significant prevalence of high-grade intraepithelial lesions (HSIL), although not the most frequent, and discontinuity on the part of the patients who obtained this result. In addition, there was a large referral to tertiary care, which is not indicated by the Ministry of Health.(AU)

Riesgo de desarrollar LIE-AG en pacientes con tamizaje inicial positivo para VPH y citología cervicovaginal negativa en seguimiento hasta 10 años: revisión sistemática y metaanálisis / Risk of developing H-SIL in patients with initial positive screening for HPV and negative cervicovaginal cytology in follow-up up to 10 years: systematic review and meta-analysis

Resumen Introducción: El cáncer de cérvix es el segundo en frecuencia y el tercero en mortalidad; la infección por el virus del papiloma humano (VPH) está asociada al riesgo de cáncer; sin embargo, no se conoce el riesgo acumulado a 1, 2, 3, 5 y 10 años. Objetivo: Determinar el riesgo de las pacientes VPH positivo con evaluación inicial citológica negativa para desarrollar lesión intraepitelial de alto grado a lo largo del tiempo. Método: Se realizó una revisión sistemática de artículos en inglés y español de los últimos 20 años, usando las bases de datos PubMed, Cochrane, LILACS, ProQuest y Embase. Se incluyeron ensayos clínicos aleatorizados en los que se determinaba el estado VPH y se realizaba seguimiento con citología cervicovaginal a 1, 2, 3, 5 y 10 años en mujeres de 20-64 años. Resultados: Se incluyeron siete ensayos clínicos aleatorizados, con un total de 98.521 mujeres, de ellas 8820 VPH positivo y 89.701 VPH negativo al ingreso, seguidas hasta por 10 años con citología cervicovaginal, encontrando que la infección por VPH es un factor de riesgo para desarrollar lesiones intraepiteliales de alto grado a 2, 5 y 10 años, con un riesgo relativo de 110.94 (79.41-154.97), 83.65 (55.22-126.73) y 29.71 (5.72-154.33), respectivamente. Conclusiones: La infección por VPH es un factor de riesgo importante para el desarrollo de lesiones intraepiteliales de alto grado a 2, 5 y 10 años.

Abstract Introduction: Cervical cancer is the second in frequency and the third in mortality, infection by the human papillomavirus (HPV) is associated with the risk of increased cancer; however, the cumulative risk of 1, 2, 3, 5 and 10 years is not known. Objective: To determine the risk of HPV-positive patients with negative initial cytological evaluation for developing high-grade intraepithelial lesion over time. Method: A systematic review of articles in English and Spanish in the last 20 years was carried out, using the PubMed, Cochrane, LILACS, ProQuest and Embase databases. Randomized clinical trials were included in which HPV was performed and subsequent follow-up with cervicovaginal cytology at 1, 2, 3, 5 and 10 years in women aged 20-64 years. Results: Seven randomized clinical trials were included, a total of 98,521 women, 8820 with positive HPV and 89701 negative on admission and followed up for up to 10 years with cervicovaginal cytology. Finding that HPV infection is a risk factor for developing high-grade intraepithelial lesion at 2, 5 and 10 years with a relative risk of 110.94 (79.41-154.97), 83.65 (55.22- 126.73) and 29.71 (5.72-154.33), respectively. Conclusions: HPV infection is an important risk factor for the development of high-grade intraepithelial lesion at 2, 5 and 10 years.

Lesão intraepitelial de alto grau na gravidez: condutas e achados durante a gravidez e pós-parto / High-grade intraepithelial injury in pregnancy: conduct and findings during pregnancy and post-childhood

Objetivo: Relatar o acompanhamento de gestação planejada, parto e puerpério de paciente em seguimento prévio a gestação de lesão intraepitelial de alto grau (câncer in situ) após realização de conização e reconização, com persistência da lesão. Métodos: Foi realizada análise de prontuário da paciente e comparação da evolução com a bibliografia. Resultados: A paciente foi acompanhada com colpoci- tologia oncológica, desde o diagnóstico de gravidez até o puerpério, apresentando resultados negativos para neoplasia. Conclusão: A decisão da paciente de gestar foi respeitada e ela teve assistência e cuidados durante todo o pré-natal, com seguimento e controle da sua lesão. Tal decisão poderia comprometer seu futuro se a lesão evoluísse. Porém, com a regressão total, pode-se pensar que a paciente poderia ter perdido a oportunidade de gestar, com um desfecho favorável, além de ser submetida a um procedimento cirúrgico definitivo importante, com conse- quências psicológicas.(AU)

Objective: To report on the follow-up of planned pregnancy, childbirth and the puer- perium of a patient who was following the pregnancy prior to pregnancy of a high- -grade intraepithelial lesion (cancer in situ) after conization and reconditioning, with persistence of the lesion. Methods: Analysis of the patient's medical record and com- parison of progress with the bibliography was performed. Results: The patient was followed up with oncological colpocytology, from the diagnosis of pregnancy until the puerperium, showing negative results for neoplasia. Conclusion: The patient's decision to gestate was respected, and she had assistance and care throughout the prenatal period, with follow-up and control of her injury. Such a decision could jeo- pardize your future if the injury evolves. However, with total regression, it can be thought that the patient could have missed the opportunity to gestate, with a favo- rable outcome, in addition to undergoing an important definitive surgical procedure and its psychological consequences.(AU)

Características citológicas previas al diagnóstico de cáncer de cérvix en mujeres de Medellín (Colombia) / Cytological characteristics prior to the diagnosis of cervical cancer in women from Medellin (Colombia)

Resumen Introducción: Actualmente, el cáncer de cérvix sigue siendo una enfermedad importante por su incidencia y mortalidad. Aunque se conoce su etiología generada por la infección del virus del Papiloma Humano (PVH) y sus métodos de tamizaje como la citología convencional y el test de ADN-PVH, aún es necesario reconocer diversas características que se relacionan con la aparición de este tipo de cáncer. Objetivo: Describir las características citológicas previas al diagnóstico de cáncer cervical en mujeres de una institución de salud de la ciudad de Medellín. Materiales y métodos: Estudio descriptivo. Se tomaron los registros clínicos correspondientes a mujeres con diagnóstico confirmado de cáncer de cérvix entre 2012 y 2017 y se revisaron los resultados de citología previos al diagnóstico. Se realizó análisis univariado para describir las variables de estudio. Resultados: La muestra de mujeres con cáncer fue de 714, la mediana de edad fue 51 años (rango intercuartílico: 42-60), la alteración citológica más frecuente fue lesión intraepitelial de alto grado (33,8%), el principal cáncer diagnosticado fue carcinoma escamocelular (70,6%). Conclusiones: Los resultados de citología alteradas son un indicador para riesgo de cáncer de cérvix, de ahí la importancia de continuar con el protocolo de tamizaje establecido.

Abstract Introduction: Currently, cervical cancer continues to be an important disease because of its high incidence and mortality. Even though its etiology (Human Papilloma Virus infection) and screening methods (conventional cytology and HPV-DNA test) are well known, understanding the various characteristics associated with the appearance of cervical cancer is fundamental. Objective: To describe the cytological characteristics that precede the diagnosis of cervical cancer in women diagnosed in a health care institution from the city of Medellín. Materials and methods: A descriptive study. The clinical records corresponding to women with a confirmed diagnosis of cervical cancer between 2012 and 2017 were used. Also, the citology results obtained before the diagnosis were reviewed. An univariate analysis was carried out in oder to describe the study variables. Results: The sample size of women with cervical cancer was 714, the age median was 51 years old (interquartile range: 42-60), the most frequent cytological alteration was high-grade intraepithelial lesion (33.8%), and the main diagnosed cancer type was squamous cell carcinoma (70.6%). Conclusions: Results showing an altered cytology are indicators of cervical cancer risk. Therefore, it is important to continue with the stablished screening protocol.

Citologia oncótica cervicovaginal na população lésbica e transgêneros / Cervicovaginal oncotic cytology in the lesbian and transgender population

O câncer de colo uterino causa a morte de milhares de mulheres no mundo. Entre essas mulheres, há grupos como o de lésbicas e transgêneros que têm dificuldade no rastreio devido à discriminação e ao desconhecimento. As lésbicas e transgêneros masculinos que não fizeram histerectomia total devem se manter no rastreio da mesma forma que as mulheres cisgêneros. Transgêneros femininos devem ser seguidas, porém ainda não há protocolos definidos.(AU)

Cervical cancer causes the death of thousands of women worldwide. Among these women, there are groups, like lesbians and transgenders that present difficulty in screening due to discrimination and lack of knowledge. The lesbians and transgenders men who didn´t have total hysterectomy, must keeping in screening the same way as cisgenders. Transgender woman must be followed, but there aren't definitive guidelines.(AU)

Adenocarcinoma cervical in situ: abordagem na atenção primária e secundária à saúde / Cervical adenocarcinoma in situ: approach in primary and secondary health care

O adenocarcinoma cervical in situ é uma doença rara, totalmente curável, diagnosticada predominantemente por meio de rastreamento cervicouterino seguido de biópsia guiada por colposcopia e/ou conização. O tratamento em pacientes que desejam preservar a fertilidade pode ser realizado num contexto ambulatorial; aquelas com paridade definida deverão ser abordadas em nível terciário.(AU)

Cervical adenocarcinoma in situ is a rare, fully curable disease diagnosed predominantly through cervical-uterine screening followed by colposcopy-guided biopsy and/or conization. Treatment in patients wishing to preserve fertility may be performed in an outpatient setting; those with defined parity should be approached at the tertiary level.(AU)

Pathologic discrepancies between colposcopy-directed biopsy and loop electrosurgical excision procedure of the uterine cervix in women with cytologic high-grade squamous intraepithelial lesions / 부인종양

OBJECTIVE: To investigate pathologic discrepancies between colposcopy-directed biopsy (CDB) of the cervix and loop electrosurgical excision procedure (LEEP) in women with cytologic high-grade squamous intraepithelial lesions (HSILs).METHODS: We retrospectively identified 297 patients who underwent both CDB and LEEP for HSILs in cervical cytology between 2015 and 2018, and compared their pathologic results. Considering the LEEP to be the gold standard, we evaluated the diagnostic performance of CDB for identifying cervical intraepithelial neoplasia (CIN) grades 2 and 3, adenocarcinoma in situ, and cancer (HSIL+). We also performed age subgroup analyses.RESULTS: Among the study population, 90.9% (270/297) had pathologic HSIL+ using the LEEP. The diagnostic performance of CDB for identifying HSIL+ was as follows: sensitivity, 87.8%; specificity, 59.3%; balanced accuracy, 73.6%; positive predictive value, 95.6%; and negative predictive value, 32.7%. Thirty-three false negative cases of CDB included CIN2,3 (n=29) and cervical cancer (n=4). The pathologic HSIL+ rate in patients with HSIL− by CDB was 67.3% (33/49). CDB exhibited a significant difference in the diagnosis of HSIL+ compared to LEEP in all patients (p<0.001). In age subgroup analyses, age groups <35 years and 35–50 years showed good agreement with the entire data set (p=0.496 and p=0.406, respectively), while age group ≥50 years did not (p=0.036).CONCLUSION: A significant pathologic discrepancy was observed between CDB and LEEP results in women with cytologic HSILs. The diagnostic inaccuracy of CDB increased in those ≥50 years of age.

Diagnóstico y tratamiento de las lesiones intraepiteliales escamosas de alto grado del cuello uterino / Diagnosis and treatment of high grade squamous intraepithelial lesions of uterine cervix

INTRODUCCIÓN. El cáncer cérvico-uterino tiene una fase precursora de larga duración, pues debe pasar por varios estados previos al cáncer invasivo, denominados lesiones intraepiteliales, de bajo y de alto grado, que pueden transformarse en lesiones malignas. La importancia de un diagnóstico oportuno y certero de las lesiones intraepiteliales escamosas de alto grado radica en que, si son tratadas de manera oportuna, son ciento por ciento curables. OBJETIVO. Proporcionar información actualizada sobre el diagnóstico y tratamiento de las lesiones precursoras de cáncer de cérvix y ayudar a los profesionales en la toma de decisiones médicas. MATERIALES Y MÉTODOS. Estudio de revisión de 45 artículos científicos la gran mayoría de la última década y, unos pocos, con datos históricos vigentes sobre lesiones intraepiteliales escamosas de alto grado del cuello uterino. La búsqueda se realizó en MedLine, PLoS y Scielo utilizando los términos tamizaje, neoplasias uterinas, lesiones intraepiteliales escamosas de cuello uterino y tratamiento. RESULTADOS. Los artículos científicos fueron seleccionados por niveles de evidencia 1 y 2, con recomendaciones A y B. Las recomendaciones de inicio de tamizaje han cambiado y el manejo toma en cuenta el riesgo acumulado por tipo de lesión. El tratamiento, en la mayoría de casos, es la escisión y resulta definitivo. CONCLUSIÓN. El diagnóstico sigue siendo cito-colpo-histológico y el tratamiento depende de la edad de la paciente, pudiendo las posibilidades ir de la observación hasta la escisión quirúrgica y, en casos específicos, la histerectomía.

INTRODUCTION. Cervical-uterine cancer has a long-term precursor phase, as it must go through several states prior to invasive cancer, called intraepithelial lesions, low and high grade, which can become malignant lesions. The importance of a timely and accurate diagnosis of high-grade squamous intraepithelial lesions is that, if treated in a timely manner, they are one hundred percent curable. OBJECTIVE. Provide updated information on the diagnosis and treatment of precursor lesions of cervical cancer and assist professionals in medical decision making. MATERIALS AND METHODS. Review study of 45 scientific articles the vast majority of the last decade and, a few, with current historical data on high-grade squamous intraepithelial lesions of the cervix. The search was conducted in MedLine, PLoS and Scielo using the terms screening, uterine neoplasms, squamous intraepithelial lesions of the cervix and treatment. RESULTS. The scientific articles were selected by levels of evidence 1 and 2, with recommendations A and B. The recommendations for starting screening have changed and management takes into account the accumulated risk by type of injury. The treatment, in most cases, is excision and is definitive. CONCLUSION. The diagnosis is still cyto-histological and the treatment depends on the age of the patient, and the possibilities may range from observation to surgical excision and, in specific cases, hysterectomy.

Anal dysplasia among solid organ transplant recipients; a cross sectional study / Displasia anal entre receptores de transplantes de órgãos sólidos - um estudo transversal

ABSTRACT Introduction: The incidence of anal cancer in United States has increased over of the last few decades impacting immunosuppressed populations like solid organ transplant recipients, in particular. The aim of this study was to evaluate the prevalence of anal dysplasia among solid organ transplant patients. We also attempted to identify factors that predispose solid organ transplant recipients to developing anal dysplasia. Methods and materials: Patients presenting to transplant office for routine care were recruited to participate in the study. All anal cytology specimens were collected using standard anal pap technique. The results were assessed using Bethesda classification. Information on perceived risk factors for development of anal dysplasia among our subjects was obtained. Results: Among 80 patients approached, 47 agreed to participate in the study. Of all the samples 19.1% had an inadequate amount of specimen to perform any analysis. Dysplastic cells were found in 10.5% of the specimens available for analysis. We were not able to identify any risk factors including age, gender distribution, smoking, and duration of immunosuppression that were statistically significant different between patients with anal dysplasia versus those without anal dysplasia. Conclusions: The rate of anal dysplasia detectable on cytology is high enough to warrant anal dysplasia screening in transplant recipients, which can then be followed up with high-resolution anoscopy with biopsy. Defining a cohort of patients among solid organ transplant recipients who are at an increased risk for the development of anal dysplasia mandating screening continues to be a challenge.

RESUMO Introdução: A incidência de câncer anal nos Estados Unidos aumentou nas últimas décadas, afetando populações imunossuprimidas, especialmente receptores de órgãos sólidos. O objetivo deste estudo foi avaliar a prevalência de displasia anal entre pacientes que receberam transplante de órgãos sólidos. Os autores buscaram identificar fatores que predispõem os receptores de transplante de órgãos sólidos a desenvolverem displasia anal. Métodos e materiais: Pacientes que se apresentaram ao consultório de transplante para acompanhamento de rotina foram recrutados para participar do estudo. Todos os espécimes de citologia foram coletados usando a técnica padrão de Papanicolau anal. Os resultados foram avaliados usando a classificação de Bethesda. Foram coletados dados sobre os fatores de risco percebidos para o desenvolvimento de displasia anal entre os participantes. Resultados: Dos 80 pacientes abordados, 47 concordaram em participar do estudo. Do total de amostras, 19,1% tinham uma quantidade inadequada para realizar qualquer análise. Células displásicas foram encontradas em 10,5% dos espécimes disponíveis para análise. Não foi possível identificar quaisquer fatores de risco, incluindo idade, distribuição de gênero, tabagismo e duração da imunossupressão, que foram estatisticamente diferentes entre pacientes com displasia anal e aqueles sem displasia anal. Conclusões: A taxa de displasia anal detectável na citologia é alta o suficiente para justificar a triagem em receptores de transplante, que pode então ser acompanhada com anuscopia de alta resolução com biópsia. A definição de triagem para uma coorte de pacientes entre os receptores de transplantes de órgãos sólidos que apresentam risco aumentado para o desenvolvimento displasia anal continua a ser um desafio.

Likewise, an inverse relationship was found between the number of births, hormonal family planning and the appearance of pre-neoplastic lesions(AU)

Risk of cervical dysplasia among human papillomavirus-infected women in Korea: a multicenter prospective study / 부인종양

OBJECTIVE: Human papillomavirus (HPV) infection is the most important risk factor for cervical cancer, which progresses from precursor lesions with no symptom if left untreated. We compared the risk of cervical dysplasia among HPV-positive Korean women based on HPV types and infection patterns. METHODS: We observed participants of a 5-year multicenter prospective cohort study, comprising HPV-positive women with either atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion of the cervix at their enrollment. Follow-ups, comprising cytology and HPV DNA testing results, were included in the final analysis. Incidence was calculated for each infection pattern (persistent infection, incidental infection, and clearance). To investigate cervical dysplasia risk, we used Cox proportional hazard models adjusted for variables that were significantly different among infection patterns. From April 2010 to September 2017, 71 of 1,027 subjects developed cervical dysplasia more severe than high-grade squamous intraepithelial lesion of the cervix. RESULTS: Of these 71 subjects, persistent infection, incidental infection, and clearance were noted in 30, 39, and 2 individuals, respectively. Based on changes in DNA results during follow-up, cumulative incidence was 27.2%, 10.4%, and 0.5% for persistent infection, incidental infection, and clearance, respectively. Compared to clearance, the adjusted hazard ratios for cervical dysplasia were 51.6 and 24.1 for persistent and incidental infections, respectively (p < 0.001). CONCLUSION: Individuals persistently infected with the same HPV types during the follow-up period had the highest risk of severe cervical dysplasia. Hence, it is necessary to monitor HPV types and infection patterns to prevent severe cervical precancerous lesions.

Diagnostic Test Accuracy Review of Cytology for Squamous Intraepithelial Lesion and Squamous Cell Carcinoma of Uterine Cervix

BACKGROUND: Even though cervico-vaginal smears have been used as a primary screening test for cervical carcinoma, the diagnostic accuracy has been controversial. The present study aimed to evaluate the diagnostic accuracy of cytology for squamous intraepithelial lesion (SIL) and squamous cell carcinoma (SqCC) of the uterine cervix through a diagnostic test accuracy (DTA) review. METHODS: A DTA review was performed using 38 eligible studies that showed concordance between cytology and histology. In the DTA review, sensitivity, specificity, diagnostic odds ratio (OR), and the area under the curve (AUC) on the summary receiver operating characteristic (SROC) curve were calculated. RESULTS: In the comparison between abnormal cytology and histology, the pooled sensitivity and specificity were 93.9% (95% confidence interval [CI], 93.7%–94.1%) and 77.6% (95% CI, 77.4–77.8%), respectively. The diagnostic OR and AUC on the SROC curve were 8.90 (95% CI, 5.57–14.23) and 0.8148, respectively. High-grade squamous intraepithelial lesion (HSIL) cytology had a higher sensitivity (97.6%; 95% CI, 94.7%–97.8%) for predicting HSIL or worse histology. In the comparison between SqCC identified on cytology and on histological analysis, the pooled sensitivity and specificity, diagnostic OR, and AUC were 92.7% (95% CI, 87.3%–96.3%), 87.5% (95% CI, 87.2%–87.8%), 865.81 (95% CI, 68.61–10,925.12), and 0.9855, respectively. Geographic locations with well-organized screening programs had higher sensitivity than areas with insufficient screening programs. CONCLUSION: These results indicate that cytology had a higher sensitivity and specificity for detecting SIL and SqCC of the uterine cervix during primary screening.

The efficacy of modified Swede Colposcopic Index in prediction of high-grade lesion and cancer of cervix / 부인종양

OBJECTIVE: To evaluate the efficacy of modified Swede Colposcopic Index (MSCI) to predict high-grade lesion and cancer of cervix (CIN2+, cervical intraepithelial neoplasia grade 2 or worse) in women with abnormal cervical cytology who underwent a colposcopy. METHODS: We conducted a retrospective study and MSCI using 5 features of cervical lesions evidenced from colposcopy: acetouptake, margin and surface, vessels, lesion size, and location of lesion. Each feature was scored from cervicograhpic findings which transformation zone was completely seen. Odds ratio of each feature was obtained by logistic regression analysis. Receiver operating characteristic curve was used to assess the efficacy of summation score to predict CIN2+. An appropriate cut-off point score was assigned. RESULTS: Two hundred and twenty women were included in the study. The assigned score for each factor in level 1 to 3 was 1, 2 and 3 points with a total score of 15 points. The most appropriate cut-off points score for MSCI to predict CIN2+ was 11 points. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy using MSCI were 82.2%, 96.2%, 96.0%, 85.0%, and 90.0% respectively. CONCLUSION: MSCI showed a high efficacy for predicting CIN2+ in satisfactory colposcopy.

Cytomorphological Features of Hyperchromatic Crowded Groups in Liquid-Based Cervicovaginal Cytology: A Single Institutional Experience

BACKGROUND: Hyperchromatic crowed groups (HCGs) are defined as three-dimensional aggregates of crowded cells with hyperchromatic nuclei, and are frequently encountered in cervicovaginal liquid-based cytology (LBC). Here, we aimed to examine the prevalence of HCGs in cervicovaginal LBC and the cytomorphological characteristics of various epithelial cell clusters presenting as HCGs.METHODS: We first examined the prevalence of HCGs in a “routine cohort” of LBC cytology (n=331), consisting of all cervicovaginal LBCs accessioned over 3 days from outpatient clinics (n=179) and the screening population (n=152). Then we examined a second “high-grade epithelial cell abnormalities (H-ECA) cohort” (n=69) of LBCs diagnosed as high-grade squamous intraepithelial lesion (HSIL), squamous cell carcinoma (SCC), or adenocarcinoma during 1 year.RESULTS: HCGs was observed in 34.4% of the routine cohort and were significantly more frequent in the epithelial cell abnormality category compared to the non-neoplastic category (p=.003). The majority of HCGs represented atrophy (70%). Of the 69 histologically confirmed H-ECA cases, all contained HCGs. The majority of cases were HSIL (62%), followed by SCC (16%). Individually scattered neoplastic cells outside the HCGs were significantly more frequent in SCCs compared to glandular neoplasia (p=.002). Despite the obscuring thick nature of the HCGs, examining the edges and the different focal planes of the HCGs and the background were helpful in defining the nature of the HCGs.CONCLUSIONS: HCGs were frequently observed in cervicovaginal LBC and were mostly non-neoplastic; however, neoplastic HCGs were mostly high-grade lesions. Being aware of the cytomorphological features of different HCGs is important in order to avoid potential false-negative cytology interpretation.
